DEVICE FOR FASTENING AND LEVELING RAILWAY RALS.

To all 107mm i may concern.'

Be it known that l, lilUsNn Sanremo, a citizen ot the llrench Republic, residing at Nancy, France, have invented certain Improvements in a Device tor Fastening and Leveling Railway Rails, ot which the tollowing is a speciiication.

This invention relates vto a device for tas toning and leveling railway rails of the Vignoles type, and consists in the combination with a chair having jaws between which the rail can be supported in a more or less elevated position, ot' hard-wood wedges arranged on the sleeper at opposite sides of the chair so as to support the rail, the jaws being recessed and drilled to accommodate clamps and screws whereby the rail clamped to the supporting wedges.

Fig. l of the accompanying drawings represents a perspective view of the chair, partly 1n section, and

Fig. 2, a perspective view ot one ot the clamps.

Fig. 3 is a perspective view ot a set of rail supporting wedges, and

Fig. et, a perspective view showing the device in use.

T he chair l is provided with jaws 3 between which the rail is vertically adjustable so that it can be supported in ditlerent altitudes within thechair. The vertical thrust ot the rail is taken by wedges ot' har l-wood arranged on the sleeper at opposite sides ot the chair. rl`he taper of these wedge is chosen so that the rail will be maintained by the latter at the proper, customary inclination towards the centre of the track. ly a longitudinal adjustment of the wedges, the rail can be raised and lowered in the chair tor leveling the track. 'lo allow a large scope ol" adjustment without employing excessively long wedges, it is preferable to use sets ot short wedges, such as 6, 9 and 10 (Fig. 3), which diiler as regards thickness and act as continuations ot each other. The thinnest wedge is thicker than the sole plate e ot the chair so that it can hold the rail clear o' said sole plate.

The rail is clamped to the wedges by means ot clamping pieces 5 which are accommodated in recesses made in the jaws 3 and which are held by screws driven through the chair into the sleeper.. rlhe clamping pieces are arched so that the thrust will always be taken by the outer Serial No. 733,821.

end 8 thereotl whatever be the elevation ot' the rail within the chair. The screw aperture in the clamping piece is flared and elongate/dse as to allow the angular position oit the clamping piece to be altered without resistance on the part of the screw. 'the clamping piece is provided with aV tall head so that it can be easily reached troni between the webs of the jaw.

The holes for the clamping screws are situated in the centre line ot the jaws. Additional screw holes at the outer ends ot the chair are arranged at opposite sides oi" the centre line. The wedges are fastened by spikes driven int-o the sleeper, washers being employed to prevent the spike heads from entering the wood. rlhis arrangement allows the spikes to be easily extracted when a readjustment of' the wedge is necessary.

ln layino' the track, the rails are clamped to the wedges, and the latter are secured by means ot the spikes. letter the track has been rammed in the usual manner, releveling can take place by loosening the tastenings and readjnsting the wedges. Any deviation trom the true level can thus be easily corrected.

The improved arrangement imparts considerable tirinness to the track. The sleepers are protected trom wear, The only elements subjected to vertical concentrated stress are the wedges, and as these are made oli' inexpensive material and can be easily renewed, the track can be kept in repairs at a small cost.

rlhe construction ot the chair may be varied without departing from the spirit of the invention. lf metal or concrete crossties are used, the fastening may be effected by means ot bolts and anchors. Grooves may be made in these ties to form guides for the wedges.

lelaim:

1. A device for fastening and leveling railway rails oft the Vignoles type, comprising a chair having aws between which the rail is supported in an elevated position, wedges ot hardwood arranged at opposite sides ot the chair as supports for the rail, and means for clamping the rail to the wedges.

2. A device for fastening railway rails of the l/"ignole type to the sleepers and for leveling the same, comprising a chair havllt) ing recessed jaws between which the rail is supported in an elevated position, Wedges of hard-wood arranged on the sleeper at opposite sides of the chair as supports for the rail, clamps accommodated in the recesses of said jaws, so as to bear against the chair and against the rail foot, and clamp screws passed through the clamps and through the chair into the sleeper fo-r fastening the elements in position.

3. A device for fastening railway rails of the Vignoles type to the sleepers and for leveling the same, comprising a chair having recessed jaws between which the rail is supported in an elevated position, wedges of hard-wood arranged on the sleeper at opposite sides of the chair as supports for the rail, arched clamping members accommodated in the recesses of said jaws so as to bear with one extreme ena against the chair and with the other end against the foot of the rail, and clamp screws passed through the clamping members and through the chair into the Sleeper for fastening the elements in position.

In testimonj7 whereof I have signed my name to this specification.
